What is a crowdsensor? • Leveraging the power of the crowd • Use people as moving sensors to gather data • Smartphones are a ubiquitous plaIorm with many connecKvity possibiliKes – 22% of the world populaKon by the end of 2013 • Business Insider Intelligence, Dec 2013 – 39.6% of mobile phone users in Portugal • Marktest, Aug 2013 – 50% of the 15-‐24 age group • Marktest, Aug 2013 – These ﬁgures are growing
• Modular and stable mobile sensing plaIorm – ApplicaKon for Android OS – Cloud storage – VisualisaKon plaIorm CrowdSensor
SenseMyCity App • Internal Sensors – LocaKon: GPS, Network – MoKon: accelerometer, gyroscope, magnetometer – ConnecKvity: WiFi, cellular – Environmental: temperature, pressure, humidity • External Sensors – On-‐Board DiagnosKcs (OBD) – Vital Jacket (ECG) – Zephyr (heart rate)
Back and Frontoﬃce • Storage and visualisaKon backoﬃces • Data collecKon and storage following data protecKon guidelines – Informed consent – Privacy – Data ownership
Mobility Study • 30 day data collecKon campaign • 10 users • ≈ 40h of data • ≈ 142k GPS-‐indexed points
Aggregate Fuel ConsumpKon
# WiFi APs
Stress Assessment • Example study case with single driver – hgp://youtu.be/RLQL5ptIQiE • Example longitudinal study with quesKonnaires and recall phase – hgp://youtu.be/YygyIUXskdY
An example longitudinal study
CrowdSensor Typical Use Cases • Urban data collecKon • Longitudinal studies on speciﬁc groups – Police oﬃcers, bus drivers, ﬁremen, … • Algorithm validaKon – Machine learning – Context inference • Service acceptance, user trials
What you can do with it? • Conﬁgure the plaIorm for your own crowdsensing applicaKon – You can choose only a subset of sensors and add your own interface – You can add a workﬂow – You can add geo-‐located quesKonnaires – You can record voice answers
